Max object size 10x10x10m? Why not 16?

When creating objects there's a limit of 10x10x10m. All land-figures are dividable by 2,4,8,16 a.s.o. A 65k land is 256x256 squares (theoratically). That's 16x16m. Anyway, I was thinking it would be nice if the max size for creating any object would be 16m instead of 10m.

Many small lots are 16x32m a.s.o. which forces us to use 2 prims to make a floor or a wall (10+6 or 8+. Building small/mid-size buildings waste unneccesary many prims this way.

Maybe bigger objects causes more lag? I don't know. But fewer objects does the opposite! What I'm trying to say is that 16m max length/width/height makes more sense. And would make building a lot easier!

This is one of those eternal mysteries, like "why are sims limited to 15,000 objects rather than 16384". Making everything uniformly multiples of the same basic number (whether 2 or 10, or 13) would make SO many things so much more consistent.
